That site looks pretty good. The largest pigeon species is the Victorian Crowned Pigeon, which is the size of a big chicken

Birmingham Rollers are really fun. The majority of mine were black Baldheads. You can keep them in a rabbit hutch, but if you want to breed them, you may want a loft or kit box for the babies. Make sure they each have a perch, and a nestbox/bowl and nesting material if you want to breed them. They make pigeon feed mixes, but if you must, you can feed them a mix of wild bird seed and layer pellets. Grit is a must. If the grit doesn't have crushed oystershell, then you'll need to mix that in too. In a month or so after you get them in the cage they'll be kept in, you can let them out to fly.

thank yall so much!I love my two pigeons i have and i was wrong on what they were they are birminghiam rollers black baldies.There is a club havein a show in fort payne alabama and its a Bantm chicken,Bantam duck, and Pigeon show i think i might put my two pigeons in there and just see what happens lol.
